I have never had any problems downloading NK.bin to a WinCE5 device (Marvell XSCAL) using PB, EShell, and some TFTP tools via Ethernet or USB RNDIS in WinXP. However, in Windows Vista, when I use thes...
We know that in the solar photovoltaic grid-connected power generation system, in order to achieve the best maximum output power, the grid-connected current amplitude must change with the external env...
Human body information monitoring is an emerging field. People envision developing wireless electroencephalogram (EEG) monitoring equipment to diagnose epilepsy patients. Wearable wireless EEG can ...[Details]
Preface
Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[Details]
The hardware circuit principle is shown in Figure 1. In the specific design, each part should consider the anti-interference problem to minimize the impact of interference on the performance of the...[Details]
Due to the needs of medical development, in many cases, general thermometers can no longer meet the requirements of fast and accurate temperature measurement, such as measuring human body temperature ...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m~1kHz), audio (20Hz~20kHz), video (20kHz~10MHz), radio fre...[Details]
1 Introduction
In recent years, with the rapid growth of mobile phones and MP4 video players, it is estimated that the production of mobile phones this year will reach 1 billion units, and...[Details]
Overview
In recent years, the vigorous development of integrated circuits has created a huge space for the research and application of digital circuits. FPGA has low power consumption, high re...[Details]
Introduction
The MAX2116 P1db data is measured at specific combinations of RF and baseband gain over the adjustable range of these two gains. These data can be used to select gain control se...[Details]
Electrocardiogram is an important means of diagnosing heart disease. However, due to various reasons, it is difficult to capture abnormal electrocardiograms with ordinary electrocardiographs. Although...[Details]
With a 31-step dimming range, existing LED drivers offer good dimming capabilities, providing smooth backlight boosting or dimming effects for LCD displays. However, when the end application involv...[Details]
With the advent of the new economic era represented by the Internet, PCs have lost their former glory, and smart 3C products (Computer, Communication and Consumer) will set off a new wave. As one o...[Details]
Anyone who has owned a laptop computer will have noticed that when running on battery power, their portable device behaves differently than when running on AC mains power—the display dims, the proc...[Details]
In the process of RF transceiver application, adjusting the processing gain (PG) of the direct sequence spread spectrum communication system (DSSS) can obtain excellent anti-noise performance, whic...[Details]
Portable products are generally powered by batteries. Due to cost and size considerations, there is a trend to reduce the number and size of batteries used in design. If the number of batteries is ...[Details]
The full name of RFID is Radio Frequency Identification, which uses radio frequency to realize data transmission between programmable controller (PLC) or microcomputer (PC) and identification, ther...[Details]
